Statistics::Regression - weighted linear regression package (line+plane fitting) ++ is a multivariate linear regression package. That is, it estimates the c coefficients for a line-fit of the type y= c(0)*x(0) + c(1)*x1 + c(2)*x2 + ... + c(k)*xk given a data set of N observations, each with k independent x variables an...

Statistics::MVA::MultipleRegression - Simple Least Squares Linear Multiple Regression Module. ++

The general purpose of multiple regression is to gain information about the relationship between several independent variables (x_i) and a dependent variable (y). The procedure involves fitting an equation of the form: y = b_o + x_1 * b_1 + x_2 * b_2...
